What is claimed is: 1. In an inflator assembly, the inflator assembly including an inflator base with at least one opening passing therethrough and wherethrough an initiator assembly is disposed, the improvement comprising: the inflator base comprising a simple stamping; the initiator assembly comprising a stamped adapter, the stamped adapter comprising an outwardly extending flange and the stamped adapter extends through one of the at least one opening to dispose at least a portion of the flange adjacent the end wall; and wherein the stamped adapter is resistance welded joined with the inflator base simple stamping. 2. The inflator assembly of claim 1 wherein the inflator base simple stamping comprises an end wall wheretbrough the at least one opening is disposed, the inflator base additionally comprising a base side wall generally perpendicularly extending from the end wall and an attachment collar generally perpendicularly extending from the base side wall at a side opposite the end wall. 3. The inflator assembly of claim 2 wherein the inflator base simple stamping comprises a substantially planar end wall wherethrough the at least one opening is disposed. 4. The inflator assembly of claim 2 additionally comprising a diffuser cap attached to the inflator base, the diffuser cap comprising a top wall and a cap side wall generally perpendicularly extending from the top wall, wherein the cap side wall is attached to the base side wall. 5. The inflator assembly of claim 1 additionally comprising a cavity disposed between the flange and the end wall. 6. The inflator assembly of claim 5 wherein the outwardly extending flange is disposed at an end of the stamped adapter and the at least a portion of the flange is disposed adjacent to an outer surface of the end wall. 7. The inflator assembly of claim 1 wherein the inflator base simple stamping includes a first opening passing therethrough and wherethrough a first initiator assembly is disposed and the inflator base simple stamping also including a second opening passing therethrough and wherethrough a second initiator assembly is disposed. 8. The inflator assembly of claim 7 wherein the first and the second initiator assemblies each comprise a stamped adapter and wherein the stamped adapter of each of the first and the second initiator assemblies is resistance welded joined with the inflator base simple stamping. 9. The inflator assembly of claim 1 wherein the initiator assembly includes an initiator device joined to the stamped adapter by an injection molded material. 10. An inflator assembly comprising: an inflator base comprising a substantially planar end wall including an opening passing therethrough, a base side wall generally perpendicularly extending from the end wall, and an attachment collar generally perpendicularly extending from the base side wall at a side opposite the end wall; a diffuser cap comprising a top wall and a cap side wall generally perpendicularly extending from the top wall, wherein the cap side wall is attached to the base side wall; and an initiator assembly comprising an initiator, a stamped adapter, and a plastic initiator adapter joining the stamped adapter to the initiator, each of the initiator, the stamped adapter, and the initiator adapter is disposed partially through the end wall opening and the stamped adapter is resistance welded joined to the inflator base, the initiator adapter including a mating interface adapted to receive an electrical connector, and the mating interface is disposed within an adapter cavity formed by the stamped adapter. 11. The inflator assembly of claim 10 wherein the stamped adapter comprises an outwardly extending flange and the stamped adapter extends through one of the at least one opening to dispose at least a portion of the flange adjacent the end wall. 12. The inflator assembly of claim 11 additionally comprising a cavity disposed between the flange and the end wall. 13. The inflator assembly of claim 11 wherein the stamped adapter comprises a redrawn center portion securing an initiator. 14. The inflator assembly of claim 13 additionally comprising a cup including an open end adapted to fittingly attach around a portion of the initiator assembly. 15. The inflator assembly of claim 14 wherein the cup open end is adapted to fittingly attach around a portion of the stamped adapter. 16. The inflator assembly of claim 10 wherein the mating interface does not extend from the adapter cavity beyond an end of the stamped adapter. 17. An inflator assembly comprising: an inflator base comprising a substantially planar end wall, a first opening in the end wall, a second opening in the end wall, a base side wall generally perpendicularly extending from the end wall, and an attachment collar generally perpendicularly extending from the base side wall at a side opposite the end wall; a diffuser cap attached to the inflator base to form a chamber, the diffuser cap comprising a top wall and a cap side wall generally perpendicularly extending from the top wall, wherein the cap side wall is attached to the base side wall; a first initiator assembly disposed through the first opening, the first initiator assembly comprising a first stamped adapter disposed through the first opening and resistance welded joined to the inflator base; a second initiator assembly disposed through the second opening, the second initiator assembly comprising a second stamped adapter disposed through the second opening and resistance welded joined to the inflator base; a first cup disposed within the chamber, the first cup including an open end adapted to fittingly attach around a portion of the first initiator assembly; and a second cup disposed within the chamber, the second cup including an open end adapted to fittingly attach around a portion of the second initiator assembly. 18. The inflator assembly of claim 17 wherein the first stamped adapter comprises a first outwardly extending flange and the first stamped adapter extends through the first opening to dispose at least a portion of the flange adjacent the end wall, and the second stamped adapter comprises a second outwardly extending flange and the second stamped adapter extends through the second opening to dispose at least a portion of the second flange adjacent the end wall. 19. The inflator assembly of claim 18 additionally comprising: a first cavity disposed between the first flange and the end wall; and a second cavity disposed between the second flange and the end wall. 20.
